It also includes significant textual materials (articles and analysis) written by editor Geoffrey Blum.
In many aspects the series is similar to Carl Barks Library (CBL) but differs by being published in colour, organizing the stories by date of publication, using only unchanged artwork and containing material not used in CBL, much of it newly discovered and previously unpublished.
Blum was a contributing editor to CBL, and his familiarity with the Barks canon and its historic background is the principal reason Egmont hired him.
Blum has drawn not only on material that appeared previously in CBL but new research he has undertaken which has resulted in a number of significant discoveries and fresh perspectives on Barks and his creations.
In Norway, a six-volume follow-up series called Carl Barks Ekstra[7][8] was published 2009–2012.
